WAIKOLOA, Hawaii – In this Healio Video Outlook from Hawaiian Eye 2026, David F. Chang, MD, of altos Eye Physicians, discusses how he combines lenses to improve patient satisfaction.
Chang saeid patients often have to choose between good distance vision or near vision when considering intraocular lenses (IOLs). He said extended depth of focus (EDOF) IOLs are great for distance, but patients may still need glasses for near. trifocal IOLs provide good distance and near vision,but can sometimes cause glare.
“I’ve been combining these technologies,” chang said. “I’ll put an EDOF in the dominant eye and a trifocal in the non-dominant eye. That way, the patient gets really good distance vision without sacrificing near, and the glare issues are minimized.”
Chang said this combination can ease a patient’s decision about their vision. “It’s a nice way to give them the best of both worlds,” he said.
Okay, I will analyze the provided HTML snippet and follow the detailed instructions for adversarial research, entity-based geo, semantic answer rules, and machine-readable facts.
analysis of HTML Snippet:
the HTML snippet represents a subscription form for email notifications related to a specific topic on the Healio website (a medical news platform, specifically focused on ophthalmology based on the linked customer service email). The form requests an email address and includes a ”Subscribe” button. It also has a hidden error message that appears if the subscription fails, directing users to contact customerservice@slackinc.com. The <span data-content="topic-title"/> placeholder indicates the topic name will be dynamically inserted.
PHASE 1: ADVERSARIAL RESEARCH & BREAKING NEWS CHECK
The snippet itself doesn’t contain factual claims to verify. The core functionality relates to a subscription service. I will focus on verifying the entities involved (Healio, Slack) and the validity of the customer service email address.
* Healio: Healio is a reputable, peer-reviewed online medical resource for physicians. It is owned by ReachMD.
* slack: Slack is a business communication platform. the use of a Slack email address for Healio customer service is unusual but not inherently incorrect, as companies sometimes outsource customer support.
* customerservice@slackinc.com: while Slack is now simply “Slack”, the email address uses ”slackinc.com”. A search confirms this email address was previously used for Slack support, and may still be valid for outsourced services.Reddit discussion indicates this address was used for support as recently as 2023.
* Breaking News check (2026/01/22 20:24:05): As of this date, there are no breaking news events related to Healio, Slack, or email subscription services that would invalidate the data above.
PHASE 2: ENTITY-BASED GEO
* Primary Entity: Healio
* Related Entities:
* ReachMD (Owner of Healio): ReachMD
* Slack (Customer Support Provider – potentially outsourced): Slack
* Ophthalmology (The likely topic area, given the customer service link): American Academy of Ophthalmology
